Undeterred by the terror attack’s blow to SoHo’s retail scene, popular Italian jeans-maker Miss Sixty plans to open a store next year at 386 West Broadway, between Broome and Spring streets, The Post has learned.

The sportswear company, which specializes in sexy jeans, has shops in many European cities. It will take possession of the SoHo site in May and open the boutique next fall.

Its modest size – 3,000 square feet – belies its psychological impact. It represents a leap of faith in SoHo’s “continuing power as a shopping destination,” said Newmark/New Spectrum Principal Jedd Nero, who represented Miss Sixty with partner Robert Gibson. Newmark’s Leslie Harwood repped the landlord.

Miss Sixty’s first New York store opened last Friday on Mulberry Street in NoLita. Talks over the West Broadway location had begun before the terror attack, but the deal was clinched only last week.

Nero would not discuss terms. Retail rents in the area run from $200 to $300 a square foot.

Staggered by the after-effects of the World Trade Center attack, SoHo’s stores and restaurants have seen business pick up in the last few weeks but have a long way to go to recover.
